Nutrient stoichiometry in winter wheat: Element concentration pattern reflects developmental stage and weather

Nutrient stoichiometry in winter wheat: Element concentration pattern reflects developmental stage and weather

At least 16 nutrient elements are required by plants for growth and survival, but the factors affecting element concentration and their temporal evolution are poorly understood. The objective was to investigate i) element concentration pattern in winter wheat as affected by crop developmental stage and weather, and ii) whether, in the short term, element stoichiometry reflects the type of prece...

Silicon availability modifies nutrient use efficiency and content, C:N:P stoichiometry, and productivity of winter wheat (Triticum aestivum L.)

Silicon (Si) is known as beneficial element for graminaceous plants. The importance of Si for plant functioning of cereals was recently emphasized. However, about the effect of Si availability on biomass production, grain yield, nutrient status and nutrient use efficiency for wheat (Triticum aestivum L.), as one of the most important crop plants worldwide, less is known so far. Consequently, we...

Coating seeds with endophytic fungi enhances growth, nutrient uptake, yield and grain quality of winter wheat

The aim of this study was to assess whether seed coating with microbialconsortium based on the arbuscular mycorrhizal (AM) fungus Glomus intraradicesBEG72, Glomus mossae and Trichoderma atroviride MUCL 45632 could improveseedling establishment, yield and grain quality (protein content and mineralcomposition) of wheat (Triticum durum Desf.). As a first step, a laboratoryexperiment was conducted ...

Nutrient stoichiometry shapes microbial coevolution

Nutrient limitation and stoichiometry of carnivorous plants.

The cost-benefit model for the evolution of carnivorous plants posits a trade-off between photosynthetic costs associated with carnivorous structures and photosynthetic benefits accrued through additional nutrient acquisition. The model predicts that carnivory is expected to evolve if its marginal benefits exceed its marginal costs. Further, the model predicts that when nutrients are scarce but...
